A Fine Line: An Ends World Novel, Book 3 Kindle Edition
I didn’t mean for anyone to get hurt.
That wasn’t my intention.
And I knew he would come for me.
Was it too much to hope he would just forget about me and everything that transpired between us.
Forget about my betrayal.
Probably.
Because here I am… In a box.
And he’s out there, lying in wait for me.
He wants me to bleed for him.
To purge my soul.
He wants his pound of flesh, but what he doesn’t know is that I have already sacrificed everything.
My body, my soul, just to save the person I love the most.
And I have nothing left to give.
Tony
She thinks I've forgotten, and that I'll just let it go.
But how can I forget about the worst kind of betrayal?
The death of someone I cared about.
So I will push her to the point of desperation, to the point of no return.
I will break her against my cold, dead heart and see what lies beneath her calm façade.
She will suffer my depravity.
She will never see me coming.
PLEASE NOTE: A Fine Line is an interconnected standalone in the Ends World Series featuring Tony Andersen. This is a spicy, suspenseful romance with mafia themes, hate with benefits, found family, vigilante effery, and violence and stuff....

About the author

MercyAnn Summers has been writing in one capacity or another for most of her life, but she didn't publish her first novel until she was almost 200 years old. Now that she's gotten used to pantsing her way through a storyline, she feels more confident in her ability to weave a decent plot with adequate humor and a decent amount of spice. She knows she's not funny. It's okay.
She lives in the frigid northeast, and she's not super happy about it.

- Reviewed in the United States on July 21, 2024Format: KindleVerified PurchaseIf MercyAnn writes it, I will read it. This slow burn with all the family focuses on Tony and Carolina. Tony is more than he appears and Carolina is up for the task. By now you should know the task.. :) There is danger afoot when the challenges of old traitors come back to resolve issues in a way we'd rather not engage.
Carolina is working her own fafo when new information and old lost things come into play. This book is a delight. It begins with shackles and ends the same way; but this time the happy " I'm gonna put you in a box" kind. Adventure, drama, unalivement and spice. All wrapped up in a bow. Laughing along the way. Well done MercyAnn. 5 happy stars!
- Reviewed in the United States on November 13, 2024Format: KindleThere is just something about this series, and this authors writing, that has me wanting to read more and more by her. I read the books out of order, because I started with book 4, which got me interested in all the other characters who were obviously in books 1 through three.
this time around, we get Tony and Carolina’s story. As with the previous books, we know that this group of friends have definite specific skill sets, and reputations to go along with them, but we don’t always get the details. I think that’s what keeps me reading . It’s just this mystery that’s not a mystery, but you want to solve it, knowing you never will. I don’t even know if that makes sense.
Tony and his group of friends do their typical FAAFO which has become a phrase I like to use in real life now.
If you are looking for something different to read, that has an intriguing storyline, and grips you without you realizing it, then this book, A Fine Line, plus the ones that came before it are probably right up your alley.
I am heading off to read book 5 since I’ve already read book 4. I need to see what happens with Matt now.
- Reviewed in the United States on December 3, 2024Format: KindleVerified PurchaseTony and Carolines story. I can't say I was excited about Tony. But he grew on me and now I think I like him. I love Caroline. Can't beat the original couple but these two really add to the team dynamic. The whole box thing is very odd, but they do them. 😆
I agree that if Mercy puts it out I will read. I have enjoyed all of these.
- Reviewed in the United States on January 27, 2024Format: KindleVerified PurchaseI found out about this book without having read the previous two in series so I went back and read those first. I am so glad I did because it made the anticipation of this book so much better. The whole series was amazing and kept you guessing with each twist. But this book was by far my favorite of the three. I loved the progression of Tony and Carolina’s characters as well as the action mixed in with spice. All main characters are likable and have such great chemistry. This book has it all: humor, action and romance. Highly recommend and looking forward to read more by this author.
- Reviewed in the United States on January 21, 2024Format: KindleVerified PurchaseThis was a fantastic book 3 in the Ends World Novels.
Tony! What a mean, grumpy, TEDDY BEAR. He hides it so well. He has a soft spot he doesn't want people to see. His interactions with Flora, melt your heart.
Carolina, man she had it rough and she still could see the good in people. Even if she was still wary of them.
Be on the ride of your life with this one. Drama, suspense, what the heck, and spice, with the HEA.
Thank you for writing this and including me on your journey.
- Reviewed in the United States on June 27, 2024Format: KindleVerified PurchaseI was not prepared for Tony’s book. The way I fell in love with his character immediately 🥵 Tony was intense and protective and everything I needed and more for his story. The story between Tony and Carolina was full of twist and turns just like Darius and Antoinette’s and I was hooked from the beginning.
- Reviewed in the United States on February 7, 2024Format: KindleIn "A Fine Line" by MercyAnn Summers, readers are plunged into a gripping tale of revenge, redemption, and unexpected passion. Tony and Carolina, once bitter enemies from a previous installment, find themselves entangled in a web of desire and danger as Tony grapples with his desire for revenge and his growing attraction to Carolina.
The dynamic between Tony and Carolina crackles with tension from the very first page, as Tony wrestles with his desire to exact vengeance upon her for what he perceives as a past wrong. However, as Tony delves deeper into Carolina's world, he begins to uncover layers of complexity and nuance, forcing him to confront his own preconceptions and prejudices.
What sets "A Fine Line" apart is its exploration of morally ambiguous characters and the gray areas of right and wrong. As Tony and Carolina's relationship evolves, readers are drawn into a complex dance of power and desire, where lines between love and hate blur and motivations are called into question.
Summers' prose is electric and unflinching, capturing the raw intensity of Tony and Carolina's connection with searing clarity. While the novel delves into dark and challenging themes, including revenge and trauma, Summers handles these topics with sensitivity and depth, offering readers a compelling exploration of the human psyche.
It's important to note that "A Fine Line" may contain triggers for some readers, particularly those sensitive to themes of revenge and manipulation. However, for fans of enemies-to-lovers romances, mafia intrigue, and darkly passionate encounters, this book is sure to captivate and enthrall.
In conclusion, "A Fine Line" is a riveting read that will keep readers on the edge of their seats from start to finish. MercyAnn Summers has crafted a dark and compelling romance that lingers in the mind long after the final page is turned, making it a must-read for fans of the genre.

5.0 out of 5 stars How can I move on from this?
Format: KindleVerified PurchaseA Fine Line, I devoured this book within 48hours and it was only that long due to having to work. Wowwwww the Turns and the twists, the spice, character development and the return of faves such as Darius and Toni with the introduction of Declan!! Oooo I loved every minute of it, if you’re prone to getting lost, Mercy Ann is your girl because the moment I feel like I don’t know what’s going on she references it out for you and you never miss what happens. I did not want this to end at all. The Epilogue was amazing as well, I was blushing so hard, do men like this exist? Where can I find one. By Far the BEST books I have read in a long time. The story doesn’t just fall around the smut, it has character and is beyond good, if you are looking for a crime/Mafia/ underground read that hits with page this is for you!!!!
Mercy Ann Summers has now become my instant read authors - you never miss the mark!

5.0 out of 5 stars Amazing Dark Read!
Format: KindleVerified PurchaseThis book is connected to the world we were introduced and thrown into with the Ends World Duet. It is a standalone, but I think people would enjoy this read so much more if they started with Ends of Being because the relationships are so interconnected and complex. I do also think that if you start at this book, you will still love it and it will have you circling back to the Ends of Being.
This book is just as fast-paced and gripping as the previous books. I love how involved the previous characters we met continue to be and that we continued to get to see where they are at through the eyes of Tony and Carolina. This is a dark, hot read, so please check the trigger warnings. You may also want to set aside a chunk of time because I read this book in one sitting - that’s how good it is! This isn’t a small book, but I could not put it down! There is action, heat, darkness, and humour. You will start on a rollercoaster ride that you just can get off of. I am now counting down the days to the release of Declan because I need more!

4.0 out of 5 stars Brilliant read.
Format: KindleVerified PurchaseThis book. Oh my gosh. I’m not even sure where to start. I loved the chemistry between Tony and Carolina. Watching Tony struggle with his feelings for her was entertaining and his relationship with Flora made my heart melt. Then, the twists. The turns. The jaw-dropping revelations! They just kept coming and at moments I just had to take a moment to process. I very much enjoyed this read and I can’t wait to see what else is in store for this rag-tag bunch!
- Jadin CoxReviewed in Canada on April 1, 2024
4.0 out of 5 stars just enough spice
Format: KindleVerified PurchaseI liked how this book has spice but it wasn’t over powering and there was still a plot. It was nice that it could be a standalone book but I would recommend reading the other books first to help make more sense of the story.

5.0 out of 5 stars Another great story
Format: KindleVerified PurchaseI fell in love with Tony in the first book of the series, but this book made me love him even more.
He struggles with his feelings quite badly in this story and you never truly knew if he hated Carolina or loved her. But I guess they do say there’s a ‘fine line’ between love and hate for a reason.
Carolina has had an awful life and has not known much kindness or love. Tony shows her that there are different ways of loving someone.
I loved the storyline for this book. A lot of drama and trauma.
Was so happy to have an unhinged Antoinette trying to help Carolina.
Bit gutted that their foursome party got interrupted lol. I wanted to see just how far Dare and Tony would go for their women.
A great world that Mercyann has created and looking forward to reading about Declan!
